Why Is My Heat Pump So Noisy When It Runs in Star City, AR?

It’s normal for a heat pump to make some clicking noise when it starts to cool your home in Star City, AR. However, the cycle should be consistently quiet. A noisy heat pump indicates a severe problem that requires fixing. Read on to learn about these heat pump noises and what they mean:

Rattling: Loose or Out-of-Balance Parts

One common sound you might hear is rattling, which is usually the result of loose screws, especially on the control panel. It’s a minor fix, something that our service tech can take care of during an annual maintenance visit.

Maybe it’s a banging sound, like metal on metal. In this case, your system may have an out-of-balance fan blade hitting other components. Act quickly to address this issue as it can cause premature wear and tear on your heat pump.

Grinding: Lack of Lubrication on Bearings

The bearings for your blower motor need oil or they won’t do their job properly. They may cause the system to overheat and shut down prematurely. In the meantime, they’ll tend to make a grinding noise.

Hissing: Refrigerant Line Leak

Hissing or whistling will happen when there’s a leak in the piping that carries refrigerant. If your home isn’t getting cool, this could be due to low refrigerant levels. Refrigerant is toxic, so rely on a professional to fix this issue.

Clicking: Electrical Issues

We mentioned clicking, which can indicate a problem if it persists into the cycle. Usually, it’s an electrical issue, such as a problem with the relay.
